Description
Technical field
The present invention relates to security device fields, are in particular a kind of handheld metal detections with posture perception function
Device.
Background technique
Handheld metal detector is widely used in the public places such as subway, airport, station, customs, hiding for detecting
Metal with human body.When Handheld metal detector detects metal, detector issues immediately or sound
Sound, light or vibration mode alarm, remind safety inspector to pay attention to.
For the occasion of big flow densely populated place, the daily workload of safety inspector is very big, and detection result also once detects
Device leaves metal or prohibited items, and alarm also stops immediately.It had been bright at that time that actually detection result, which only has safety inspector,
, once detection process terminates, testing result disappears, and can not accomplish classification and statistics to detection process, to testing result
It can not carry out data analysis.Meanwhile if the related datas such as each detection process, testing result have record, have preservation,
Critically important effect can also be played to the examination and assessment of security staff.
Summary of the invention
The technical problem to be solved is that deficiency in the prior art is overcome, providing one kind can determine to pacify this patent automatically
The Handheld metal detector with posture perception function whether inspection process is completed.
For solve prior art problem, this patent the technical solution adopted is that: a kind of hand-held with posture perception function
Metal detector, including shell and it is mounted on the intracorporal detecting element of shell, microcontroller, alarm and battery component, the shell
Body forms detecting area, component region and handle region interconnected, and the microcontroller is arranged in component region, the component region also
Equipped with Inertial Measurement Unit and magnetic sensor, the Inertial Measurement Unit connects microcontroller with magnetic sensor.This patent
By the way that Inertial Measurement Unit and magnetic sensor for measuring metal detector motion state itself are arranged in detector, into
One step understands the specific motion conditions of metal detector, avoids metal detector during the motion because not reaching specific
Region and the missing inspection situation occurred.
The Inertial Measurement Unit includes three-axis gyroscope sensor and 3-axis acceleration sensor.The three-axis gyroscope
Sensor can measure motion track of the metal detector in solid space and the angular acceleration relative to navigational coordinate system,
The 3-axis acceleration sensor can measure the acceleration of metal detector independent three axis in a coordinate system.Therefore, lead to
Cross three-axis gyroscope sensor and 3-axis acceleration sensor can understand metal detector in the motion track of solid space and
Various velocity informations.
Further, the magnetic sensor is triaxial magnetic field sensor.The triaxial magnetic field sensor can be according to gold
The magnetic field strength for belonging to detector different location in solid space is different, to further obtain metal detector present position letter
Breath.
Further, it is equipped in the microcontroller for reading and analyzing the Inertial Measurement Unit and magnetic sensor
The control chip of measurement result.Control chip metal detector according to measured by Inertial Measurement Unit and magnetic sensor
Motion profile, movement velocity and locating orientation data information, and then judge whether primary completely safety check process is completed.
When metal detector is when unfinished safety check works and leaves working region, the control chip will first close information feedback to alarm
Device causes relative alarm prompt.
The shell is equipped with the miniature webcam for shooting detected object.The miniature webcam is mounted on the portion
Part area side.Since miniature webcam is smaller, it is difficult to discover under relatively remote, it, can be real when detected object is emphasis inspector
Existing more covert shooting.In addition, including at least a pair of of miniature webcam, it is distributed in the component region two sides.It is visited in this way in metal
It surveys in device detection process, omnidirectional shooting can be carried out to detected object, avoid the occurrence of key area and picture leakage occurs and claps feelings
Condition, to realize that entire safety check process and important detected object have image frame and videograph.
Data storage device is equipped in the component region.The data storage device can protect various detection result data
It stores away, is transferred to terminal device again in the case where having suitable terminal device and signal.The detection result data packet
The status data for including Handheld metal detector itself, such as motion conditions, unused time, work total duration, battery capacity, machine
ID, self-detection result, fault message and GPS positioning information etc., further include the result data of inspected object, such as time of fire alarming,
The photos and videos data of alarm times, type of alarm etc. and inspected object.In this way, as much as possible can be collected into
Various data are conducive to the own situation for comprehensively understanding inspected object and metal detector.
The component region is additionally provided with the radio communication mold group for being used for transmission data, and the radio communication mold group includes at least
One of WIFI module, bluetooth module or mobile communications network module.Thus can have WIFI signal, Bluetooth signal,
It can be by detection result number in the case where any one in Zigbee network signal and 2G/3G/4G mobile communications network signal
According to being transferred to backstage computer terminal.Backstage computer terminal is statisticallyd analyze according to these data are further, and then in further detail
Ground understands the use state of safety check situation and metal detector, arranges safety check work and the inspection of metal detector timely and reasonably
It repairs and instrument is replaced.
Compared with prior art, this patent is arranged for measuring the used of metal detector motion state itself in detector
Property measuring unit and magnetic sensor.The specific fortune of metal detector can be obtained by Inertial Measurement Unit and magnetic sensor
Dynamic information, so that whether understand metal detector completes safety check work, detection data by wireless network transmissions to backstage,
Number detected in these data, such as unit time can be counted and be analyzed with alarm number.
